Unit 4
Gases in our atmosphere

There are thousands of gases in the troposphere.  In this unit we look in more detail at the most important components of the lower atmosphere.

Some of the gases are evenly spread all over the world, whereas the concentrations of others depends strongly on sources, local conditions and on the time of day. In this unit we give a short overview on how gases in our atmosphere can be characterised.
